Summary: Beta 20041124 Failure on Mac OS X

Initial Comment:
Immediately after launching the new drjava beta20041124 in Mac 
OS X 10.3.6 (with java.version 1.4.2_05), I get the following error 
in an error window:

---

Dr Java will then run, but the Interpreter will not run any 
programs.  The Console says this:

---
java.lang.IllegalStateException: Interpreter JVM exited before
